01  /  What you get

The number, and what it means.

Every load on the house added up the way the code says to, with the answer in amps and a plain line on whether the service you planned is enough.

  • 03Generator sizing, 3 optionsRun everything, run everything with load shedding, or the smallest unit that still starts the AC, so the owner can pick.
  • 04Gas vs electricGas appliances listed but not loaded, so the number is honest both ways.

04  /  Questions

What we need from you.

The heated square footage, which appliances are gas and which are electric, the AC size and any heat strips, and anything extra like a pool, EV charger, shop or generator. A plan set covers most of it.

It is the code's method for a single house, and it reflects how a house actually uses power. It gives a realistic service size instead of padding the number.

Yes. The same numbers give a whole house size, a smaller size with load shedding, and an AC only range, so the owner can choose with the tradeoffs in front of them.
